摘要
以莫高窟为例探讨了挡墙加固型石窟围岩及其附属构筑物的地震稳定性评价方法 .认为对于大型的石窟群及其附属构筑物 ,其地震稳定性评价宜采用以动力分析方法为主 ,拟静力法为辅的双轨制方法 ,并提出了具体的评价思路和理论分析方法 .
Taking Mogao grotto as example, the seismic resistance characteristics of retain wall type grotto is discussed. Methods for the seismic stability evaluation of surrounding rock and auxiliary structures of grottoes are studied. It is concluded that the method of dynamic analysis can be mainly used in seismic response analysis for large scale grottoes and its auxiliary structures ,at the same time,results of pseudo static analysis have to be used as reference. Furthermore, some thoughts and methods of evaluating seismic resistance ability of grottos are put forward.
